ANIMAL FORCEPS.

Application 'filed. June 14, 1926. Serial No. 115,888.

The object of my invention is to provide an animal forceps of simple,durable and comparatively inexpensive construction.

A further object is to provide a device of this kind having a pluralityof fingers which may be opened or closed as desired, each one of whichis selectively manipulated.

Still a further object is to provide an animal forceps with a convenientmeans for op erating each individual finger, said means being adjustablyarranged to suit the hand of the user. i

A further object is to provide novel features of construction for such adevice whereby the fingers are held in open position.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mydevice',whereby the objects contemplated are attained as hereinaftermore fully set forth, pointed out in my claims and illustrated in theaccompanying drawings, in which: 1 I

Figure 1 is a plan view of an animal forceps embodying my invention.

Figure 2 is a side elevation of the same.

Figure 3 is a bottom view of my forceps I illustrating the operatingthimbles.

Figure 4-is an enlarged detail sectional view taken on'the line 4-4 ofFigure 2.

Figure '5 is an' enlarged'deta'il sectional view taken onthe line 5y5 ofFigure 1; and

Figure 6 is an enlarged detail sectional view taken on the line 66 ofFigure 5.

Upon the accompanying drawing, 1 have used the reference numeral 10 toindicate generally a tubular casing upon which the parts of my inventionare mounted.

The casing 10has an open upper end 11' from which protrude a pluralityof fingers, 12, 13, 14, 15, and 16. The end 11 and the fingers justreferred to are adapted to be inserted into the uterus of a pig or otheranimal'for the removal of the animals offspring. 7

The lower ends of the fingers extend into the casing 10 and each has anout-turned portion 17 which coacts with a slot 18 in the casing 10whereby the fingers are pivoted in the slots 18. The ends 17 are rivetedas at 19 for retaining them in the slots 18. The upper ends of thefingers have knobs 20 for engaging the offspring and are well rounded onall sides to prevent injury to the animal. 7 V i For normally holdingthe fingers in open posltion, I provide a leaf spring 21 secured to eachof the fingers 12. 13, 14, 15, and 1-6 as clearly shown in Figures 1 and6.

. It will be noted that the springs 17 are within the casing 10 wherebythey are concealed and are not in the way in using my instrument. Thesprings 17 resiliently hold the fingers in open position, as the fingers'12, 14, 15, and 16 are illustrated on the drawing. I

For operating each finger towardclosing position as is illustrated bythe finger 13 in Figure 2 of the drawing, I provide a rod 24. Each rod24 has its upper end extend mg 1111:011 slot 25 in its respectivefinger. A-

pin 26 projects in opposite directions from the rod 24 into slots 27.The slots 27 open into the slot 25 as clearly illustrated in Figure 6 ofthe drawing. The rod 24 extends down to the casing 10 and is bent as at28 to extendthrough a hole 29 in the wall of the tubular casing 10. Fromthe construction of the parts just described it will be' seen that therods 24 are normally in the 7 position, of those which operate thefingers 12, 14,15, and 16 in Figure 2.

When the rods 24 are moved upward as illustrated by the one whichoperates the finger 13, its respective finger will be moved 1 towardclosedposition. The lower end of the rod 24 is threaded as at 30 andterminates just below a conical flange 31 which is formed on the lowerend of the tubular casing 10.

iA nut 32 is screwed onto the threaded end 30 ofthe rod 24 and has ears33 formed thereon. A lever 34 is pivotally secured between the ears 33by a cotter or pin 35. The lever 34 is pivoted between ears 36 which issecured adjacent the outer edge of the washer 31. The, conical shape oftheifiange 31 allows considerable pivotal movement of the lever 34. Thelever 34 has a downwardly extending portion 37 to the lower end of whichis secured a tubular member 38 which is similar to a thimble with theexception that it doesnt have a closed end,

It will be noted by referring to Figure 3 that there are live levers31-, to four of which are secured the thimhles 3S and to the remainingone is secured a similar thimhlo 39. The thinibles 38 and 39 are roundedas at sit) and have an inwardly projecting flange 41 on their upperends.

The thimbles 4-0 are :ulapl'ed to receive the lingers of the hand of theoperator as illustrated in dotted lines in Figure l and the thinible 39is adapted to receive his thumb.

In the use of my device the lingers 1:2, iii, lal, 15 and 16 arenormally held open h v the springs and the fingers and thuinli oi: theoperator are placed in their proper thimbles. \Vhen it is desired toclose any oi? the fingers 12, 1-3, 11, 15 or 16. the proper thimhle isdrawn toward theccnter as shown by the arrow -12 in Figure 3. Then ifthe entire hand is closed by a list closing move ment all the lingers12, 13, 11, 15 and 16 are moved toward closing position.

It will thus be seen that I have provided an animal forceps having aplurality oi tingers, each ofwhich is convenii-mtly operated greaterforce may be applied to the fingers 12,13, 14, 15, and 16 without undueeffort on the partof the operator. By nialtin the thimbles 38 and 39open, the fingers may extend theret-hrough So thatmy forceps ma besupported and operated and can be either inserted or withdrawn with onehand.

Some changes may he made in the construction and arrangementofthe'arious parts of my animal forceps Without departing from the realspirit and purpose of my invention and it is my intention to cover by myclaims, any modified forms ofstructure last means comprising thimhlesadjustahly connected to said lingers.

An animal forceps of the class described comprising a tubular rasing,lingers pivoted at one end thereof, and spring act'nated toward openposition. a flange at the other end thereof, rods slidably mountedthrough said casing, levers pivoted to said i'lann'e and to the ends ofsaid rods. said rods extending through slots in said tubular casing andconnected to said pivoted lingers whereby movement oli said leverstoward the axis line of said casing will cause said lingers to close.

4. An animal li'oreeps oi the class d escribed comprising a tubularcasing, .tingers pivoted at one end thereof, and spring actuated towardopen position, rods slidahly mounted through said casing, and leverspivoted to the lower end thereof and to the ends of said rods, said rodsextending through slots in said tubular casing and connected to saidpivoted lingers whereby movement of said levers toward the axis line ofsaid casing will causesaid lingers to close,

and thimhlcs mounted on thernds of said lovers adaptedlio receive thefingers and thumb of an operator. 1
